【ORACLE错误】SP2-0618: Cannot find the Session Identifier. Check PLUSTRACE role is enabled

执行set autotrace traceonly的时候，报错

SQL> set autotrace traceonly
SP2-0618: Cannot find the Session Identifier.  Check PLUSTRACE role is enabled

切换到sysdba下，授予权限

SQL> conn / as sysdba
Connected.
SQL> grant plustrace to scott;
grant plustrace to scott
